* Bluetooth: Move struct hci_pinfo into net/bluetooth/hci_sock.cMarcel Holtmann2014-07-111-0/+11
| | | | | | | | There exists no external user of struct hci_pinfo and hci_pi and thus move it into the one place that is actually using it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

| | | | | | | | | | There is only single location using struct hci_sec_filter and with that there is no point in putting this declaration into a global header file. So move it right next to its user and make the code a lot more simpler. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Unify helpers for bdaddr_list manipulationsJohan Hedberg2014-07-091-2/+2
| | | | | | | | | | | | We already have several lists with struct bdaddr_list entries, and there will be more in the future. Since the operations for adding, removing, looking up and clearing entries in these lists are exactly the same it doesn't make sense to define new functions for every single list. This patch unifies the functions by passing the list_head to them instead of a hci_dev pointer.

* Bluetooth: Run controller setup after external configurationMarcel Holtmann2014-07-061-1/+2
| | | | | | | | | | | | | | | | | | | When the external configuration triggers the switch to a configured controller, it means the setup needs to be run. Controllers that start out unconfigured have only run limited set of HCI commands. This is not enough for complete operation and thus run the setup procedure before announcing the new controller index. This introduces HCI_CONFIG flag as companion to HCI_SETUP flag. The HCI_SETUP flag is only used once for the initial setup procedure. And during that procedure hdev->setup driver callback is called. With the new HCI_CONFIG the switch from unconfigured to configured state is triggering the same setup procedure just without hdev->setup. This is required since bringing a controller back to unconfigured state from configured state is possible.

* Bluetooth: Add support for Unconfigured Index Added eventsMarcel Holtmann2014-07-031-6/+3
| | | | | | | | | | When a controller is in unconfigured state it is currently hidden from the management interface.

* Bluetooth: Introduce unconfigured controller stateMarcel Holtmann2014-07-031-4/+4
| | | | | | | | | | | | | | | | With the new unconfigured controller state it is possible to provide a fully functional HCI transport, but disable the higher level operations that would normally happen. This way userspace can try to configure the controller before releases the unconfigured state. The internal state is represented by HCI_UNCONFIGURED. This replaces the HCI_QUIRK_RAW_DEVICE quirk as internal state representation. This is now a real state and drivers can use the quirk to actually trigger this state. In the future this will allow a more fine grained switching from unconfigured state to configured state for controller inititialization.

* Bluetooth: Restrict access for raw-only controllersMarcel Holtmann2014-07-031-4/+10
| | | | | | | | | | | | | | | | | Bluetooth controllers that are marked for raw-only usage can only be used with user channel access. Any other operation should be rejected. This simplifies the whole raw-only support since it now depends on the fact that the controller is marked with HCI_QUIRK_RAW_DEVICE and runtime raw access is restricted to user channel operation. The kernel internal processing of HCI commands and events is designed around the case that either the kernel has full control over the device or that the device is driven from userspace. This now makes a clear distinction between these two possible operation modes. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

* Bluetooth: Return EOPNOTSUPP for HCISETRAW ioctl commandMarcel Holtmann2014-04-241-10/+1
| | | | | | | | | | | | | | The HCISETRAW ioctl command is not really useful. To utilize raw and direct access to the HCI controller, the HCI User Channel feature has been introduced. Return EOPNOTSUPP to indicate missing support for this command. For legacy reasons hcidump used to use HCISETRAW for permission check to return proper error codes to users. To keep backwards compability return EPERM in case the caller does not have CAP_NET_ADMIN capability.

| * Bluetooth: Fix HCI User Channel permission check in hci_sock_sendmsgMarcel Holtmann2013-12-171-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HCI User Channel is an admin operation which enforces CAP_NET_ADMIN when binding the socket. Problem now is that it then requires also CAP_NET_RAW when calling into hci_sock_sendmsg. This is not intended and just an oversight since general HCI sockets (which do not require special permission to bind) and HCI User Channel share the same code path here. Remove the extra CAP_NET_RAW check for HCI User Channel write operation since the permission check has already been enforced when binding the socket. This also makes it possible to open HCI User Channel from a privileged process and then hand the file descriptor to an unprivilged process.

* | net: rework recvmsg handler msg_name and msg_namelen logicHannes Frederic Sowa2013-11-201-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

* Bluetooth: Introduce new HCI socket channel for user operationMarcel Holtmann2013-09-161-5/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introcuces a new HCI socket channel that allows user applications to take control over a specific HCI device. The application gains exclusive access to this device and forces the kernel to stay away and not manage it. In case of the management interface it will actually hide the device. Such operation is useful for security testing tools that need to operate underneath the Bluetooth stack and need full control over a device. The advantage here is that the kernel still provides the service of hardware abstraction and HCI level access. The use of Bluetooth drivers for hardware access also means that sniffing tools like btmon or hcidump are still working and the whole set of transaction can be traced with existing tools. With the new channel it is possible to send HCI commands, ACL and SCO data packets and receive HCI events, ACL and SCO packets from the device. The format follows the well established H:4 protocol. The new HCI user channel can only be established when a device has been through its setup routine and is currently powered down. This is enforced to not cause any problems with current operations. In addition only one user channel per HCI device is allowed. It is exclusive access for one user application. Access to this channel is limited to process with CAP_NET_RAW capability. Using this new facility does not require any external library or special ioctl or socket filters. Just create the socket and bind it. After that the file descriptor is ready to speak H:4 protocol. struct sockaddr_hci addr; int fd; fd = socket(AF_BLUETOOTH, SOCK_RAW, BTPROTO_HCI); memset(&addr, 0, sizeof(addr)); addr.hci_family = AF_BLUETOOTH; addr.hci_dev = 0; addr.hci_channel = HCI_CHANNEL_USER; bind(fd, (struct sockaddr *) &addr, sizeof(addr)); The example shows on how to create a user channel for hci0 device. Error handling has been left out of the example. However with the limitations mentioned above it is advised to handle errors. Binding of the user cahnnel socket can fail for various reasons. Specifically if the device is currently activated by BlueZ or if the access permissions are not present.

* Bluetooth: Introduce user channel flag for HCI devicesMarcel Holtmann2013-09-161-6/+9
| | | | | | | | | | | | | | | | | | This patch introduces a new user channel flag that allows to give full control of a HCI device to a user application. The kernel will stay away from the device and does not allow any further modifications of the device states. The existing raw flag is not used since it has a bit of unclear meaning due to its legacy. Using a new flag makes the code clearer. A device with the user channel flag set can still be enumerate using the legacy API, but it does not longer enumerate using the new management interface used by BlueZ 5 and beyond. This is intentional to not confuse users of modern systems. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

| * Bluetooth: HCI - Fix info leak via getsockname()Mathias Krause2012-08-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The HCI code fails to initialize the hci_channel member of struct sockaddr_hci and that for leaks two bytes kernel stack via the getsockname() syscall. Initialize hci_channel with 0 to avoid the info leak.

| * Bluetooth: HCI - Fix info leak in getsockopt(HCI_FILTER)Mathias Krause2012-08-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The HCI code fails to initialize the two padding bytes of struct hci_ufilter before copying it to userland -- that for leaking two bytes kernel stack. Add an explicit memset(0) before filling the structure to avoid the info leak.

| | | | | | | | | | | | | | | | | | | | | | This flag is of no use right now and is in fact harmful in that it prevents the HCI_MGMT flag to be set for any controllers that may need it after the first one that bluetoothd takes into use (the flag is cleared for the first controller so any subsequent ones through the same bluetoothd mgmt socket never get the HCI_MGMT flag set).
